Hi all, In parallel of the Java 11 TCK on the actual TomEE binary, I looked at the build again. Remember that I merged a PR 2 weeks ago and ended up reverting because TomEE binaries can already work with Java 11.
So here is what I have done so far 1/ Build TomEE with JDK 8 On a terminal with JDK 8, `mvn clean install -DskipTests` 2/ Run tests with JDK 11 Started with the examples first. So in another terminal, I ran `mvn test -f examples` It fails pretty much immediately with Caused by: java.lang.ClassNotFoundException: javax.xml.bind.JAXBException at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:583) That's ok, because as specified in https://openjdk.java.net/jeps/320 JAXB with some other APIs aren't available anymore. There is a way to activate javaee modules but it's not recommended as it will disappear soon. The recommended approach is to add the dependencies straight in the project as regular dependencies. In TomEE, the interesting thing is that, the actual binaries shipped to users (zip, tag.gz) already have those dependencies so TomEE can run on IBM JVM for instance. That's the reason why I can run TCK with either JDK8 or JDK11 without any change. If you check the PR I reverted, I have added the extra dependencies inside a profile which is activated by default on Java 11. See https://github.com/apache/tomee/pull/523/files#diff-350f248c5779512fd39778551f6e5ec1R714 What do you guys think? Should add the APIs straights in the javaee-api? Add the dependencies straights without profiles? -- Jean-Louis Monteiro http://twitter.com/jlouismonteiro http://www.tomitribe.com
